C Program to Add two Integers

Given two numbers A and B. The task is to write a program to find the addition of these two numbers.


Input: A = 2, B = 3
Output: 5

Input: A = 3, B = 6
Output: 9

In the below program to add two numbers, the user is first asked to enter two numbers and the input is scanned using the scanf() function and stored in the variables A and B. Then, the variables A and B are added using the arithmetic operator + and the result is stored in the variable sum.

Below is the C program to add two numbers:





// C program to add two numbers
int main()
    int A, B, sum = 0;
    // Ask user to enter the two numbers
    printf("Enter two numbers A and B : \n");
    // Read two numbers from the user || A = 2, B = 3
    scanf("%d%d", &A, &B);
    // Calclulate the addition of A and B
    // using '+' operator
    sum = A + B;
    // Print the sum
    printf("Sum of A and B is: %d", sum);
    return 0;



Enter two numbers A and B : 2 3
Sum of A and B is: 5
